the internal PWM comparator, so the PWM comparator can control the duty
cycle. This pin also provides over-current protection. If V FB is higher than the
trigger level and persists at that level, the controller stops and restarts.
An external NTC thermistor is connected from this pin to the GND pin. The
impedance of the NTC decreases at high temperatures. If the voltage of the RT
pin drops below the threshold, PWM output is disabled.
This pin senses the voltage across a resistor. When the voltage reaches the

internal threshold, PWM output is disabled and this activates over-current
protection. This pin also provides current amplitude information for Current
Mode control.
